"While it was in training at home I saw a good deal of the Rainbow Division," he said "Then, one day, it was gone to France, where it disappeared behind the curtain of military secrecy which must be drawn unless we choose to sacrifice the lives of our men for the sake of publicity. The enemy's elaborate intelligence system seeks at any cost to learn the strength, the preparedness, and the character of our troops. Our own intelligence service assures us that the knowledge of our army in France which some assume to exist does not, in fact, exist. "If we were to announce the identity of each unit that comes to France, then we would fully inform the enemy of the number and nature of our forces. Published details about any division are most useful to expert military intelligence officers in determining the state of the division's preparedness, and the probable assignment of the division to any section. "But now it is safe to mention certain divisions which were first to arrive in France and have already been in the line. This includes the Rainbow Division, famous because it is representative of all parts of the United States. This division should find in its character an inspiration to _esprit de corps_ and general excellence. It should be conscious of its mission as a symbol of national unity. "The men of Ohio I know as Ohioans, and I am proud that they have been worthy of Ohio. A citizen of another State will find himself equally at home in some other group, and the gauge of this State's pride will be the discipline of that group of soldiers, its conduct as men, its courage, and its skill in the trenches. You may learn more than war in France. You may learn lessons from France, whose unity and courage have been a bulwark against that sinister force whose character you are learning in the trenches. The Frenchman is, first of all, a Frenchman, which stimulates, rather than weakens, his pride in Brittany as a Breton, in Lorraine as a Lorrainer, and his loyalty and affection for his own town, or village, or home. In truth he fights for his family and his home when he fights for France and civilization. Thus, you will fight best and serve best by being first an American, with no diminution of your loyalty to your State and your community. "With us at home the development of a new national unity seems a vague process compared to the concrete process you are undergoing. You are uniting North, East, South, and West in action. We aim to support you with all our resources, to make sure that you do not fight in vain." The brigade of the veterans was reviewed on the last day of the camp inspection. Secretary Baker went by motor, with officers and aides, as far as the foot of the hill from which he was to review the troops deploying in the Marne valley. Twenty days of rain had made the hilltop inaccessible by motor. As Secretary Baker started up one slope, General Pershing and his aides ascended another, and the two men met at the top.
